DETAILED DESCRIPTION OF EMBODIMENTS

Embodiments of the presently disclosed jaw restraint will now bedescribed in detail with reference to the drawings wherein like numeralsdesignate identical or corresponding elements in each of the severalviews. As is common in the art, the term ‘proximal” refers to that partor component closer to the user or operator, i.e. surgeon or physician,while the term “distal” refers to that part or component further awayfrom the user.

Referring initially to FIG. 1 there is disclosed one embodiment of a jawrestraint 10 for use with a surgical stapling instrument 12. Surgicalstapling instrument 12 generally includes a handle assembly 14 having anelongate member 16 extending distally from handle assembly 14. A loadingunit 18, including a tool or jaw assembly 20, is removably attached to adistal end 22 of elongate member 16. Jaw assembly 20 generally includesan anvil member 26 and the cartridge assembly 28. A jaw assembly 20 ismovable from an open position to a closed position in which anvilassembly 26 and cartridge assembly 28 are in close cooperativealignment. A trigger 30 is provided on handle assembly 14 to move anvilassembly 26 from the open position to the closed position relative tocartridge assembly 28. A rotation knob 32 is provided on elongate member16 in order to rotate jaw assembly 20 with respect to the handleassembly 14 and relative to the tissues being operated upon.

Jaw restraint 10 is provided to maintain anvil assembly 26 in the openposition relative to cartridge assembly 28 during shipping of loadingunit 18, in a manner described in more detail hereinbelow. Bymaintaining anvil assembly 26 and the open position relative tocartridge assembly 28, jaw restraint 10 prevents shifting of, or damageto, internal components associated with anvil assembly 26 or cartridgeassembly 28 due to bumping, crushing, etc. during shipment.

While jaw restraint 10 is described for use with surgical staplinginstrument 12, it is contemplated that jaw restraint 10 is useful withother surgical instruments having a pair of jaw members such as, forexample, surgical stapling instruments including parallel jaw members,electro-surgical instruments used to join tissue, etc.

Referring now to FIG. 2, there is disclosed an enlarged view of loadingunit 18 including tool assembly 20 and jaw restraint 10. As shown,cartridge assembly 28 includes first and second longitudinally extendingrows of staple containing pockets 34 and 36. A knife slot 38 extendslongitudinally through cartridge assembly 28 between first and secondrows of staple containing pockets 34 and 36. In this embodiment, thecartridge assembly 28 has three rows of staples on either side of theknife. It is contemplated herein that the disclosed jaw restraint can beused with cartridge assemblies having less than three rows of staples oneither side of the knife. While not specifically shown, jaw restraint 10is provided to maintain and stabilize anvil assembly 26 and cartridgeassembly 28 in order to prevent staples (not shown) from being bumped orejected out of the rows of staple containing pockets 34 and 36.

As shown, jaw restraint 10 includes a finger member 40 to facilitatemanipulation of jaw restraint 10 about anvil assembly 26 and cartridgeassembly 28. Jaw restraint 10 includes a first or upper arm 42 which isprovided to engage and stabilize cartridge assembly 26 and a second orlower arm 44 which is provided to engage and stabilize cartridgeassembly 28. The first arm 42 is arcuate in shape and forms a firstrecess “recess 42 a” for receiving the jaw of the tool assembly. Thesecond arm 44 can have a similar shape and forms a second recess “recess44 a” for receiving the jaw of the tool assembly, where the restraintengages a surgical stapling tool, the arm for engaging the cartridgeassembly has a greater depth than the other arm.

Referring now to FIGS. 3 and 4, jaw restraint 10 is at least partiallyformed of a generally flexible material in order to be easily removedfrom about anvil assembly 26 and cartridge assembly 28. Jaw restraint 10may be formed from a variety of materials such as polymeric copolymermaterials, stainless steel, shape memory alloys, etc. Additionally,while jaw restraint 10 is illustrated as formed from generally thinrectangular material, it is also contemplated that jaw restraint 10maybe formed from materials having other cross-sections such as, forexample, tubular, solid circular, etc.

A resilient portion extends between the arms 42, 44. Thus, jaw restraint10 includes a resilient inwardly facing projection 46 in this embodimentprovided between upper and lower arms 42 and 44. Inwardly facingprojection 46 is flexible relative to upper and lower arms 42 and 44.Inwardly facing projection 46 functions as a hinge and is provided tobias upper and lower arms 42 and 44 into a first or closed position.Additionally, inwardly facing projection 46 is provided to extendbetween anvil assembly 26 and cartridge assembly 28 in order to preventany relative movement there between during shipment. In the disclosedembodiment only one inwardly facing projection is shown, however, it iscontemplated that more than one inwardly projection can be used. Upperarm 42 is connected to inwardly facing projection 46 by a first arcuatemember or portion 48. Likewise, lower arm 44 is connected to inwardlyfacing projection 46 by a second arcuate member or portion 50. Wherein,the second arcuate member portion 50 has a greater depth “d” than thefirst arcuate member portion 48. Inwardly facing projection 46 also hasa generally arcuate shape facing generally in an opposite direction fromfirst and second arcuate portions 48 and 50.

In this embodiment, finger member 40 extends proximally from firstarcuate portion 48. In order to inhibit anvil assembly 26 and cartridgeassembly 28 from sliding sideways out between upper arm 42 and lower arm44, upper and lower arms 42 and 44 are provided with first and secondinwardly directed lips 52 and 54. First and second inwardly directedlips 52 and 54 are provided with respective enlarged distal ends 56 and58 to further inhibit any sideways movement of anvil assembly 26 andcartridge assembly 28 relative to jaw restraint 10.

It should be noted that, the various disclosed jaw restraints andelements of the jaw restraint, such as jaw restraint 10, may be formedas a single, integral body member or, alternatively may be formed fromseparate components joined together through various known methods suchas, for example, welding, gluing, etc.

Referring now to FIGS. 5 and 6, and initially with respect to FIG. 5,the use of jaw restraint 10 to stabilize anvil assembly 26 and cartridgeassembly 28 during shipment will now be described. As noted hereinabove, cartridge assembly 28 includes a plurality of staples 60 providedwithin first and second rows of staple containing pockets 34 and 36.First and second rows of staple containing pockets 34 and 36 are formedin a plastic body portion 62 of cartridge assembly 28. A generallyU-shaped channel member 64 is provided to support body portion 62. Anvilassembly 26 includes an upper anvil member 66 and a lower anvil plate 68which is provided to crimp staples 60.

Prior to shipment, jaw restraint 10 is positioned about anvil assembly26 and cartridge assembly 28. Specifically, upper arm 42 of jawrestraint 10 engages and secures anvil assembly 26 while lower arm 44engages and secures cartridge assembly 28. As shown, inwardly facingprojection 46 extends between anvil plate 68 of anvil assembly 26 andbody portion 62 of cartridge assembly 28 to thereby inhibit any movementof anvil assembly 26 relative to cartridge member 28 during shipping.

Additionally, first and second lips 52 and 54, along with respectiveenlarged distal ends 56 and 58, provided on upper and lower arms 42 and44, respectively, assist in preventing anvil assembly 26 and cartridgeassembly 28 from sliding sideways in the direction of arrow A out of jawrestraint 10.

Referring now to FIG. 6, in order to remove jaw restraint 10 from anvilassembly 26 and cartridge assembly 28, finger member 40 is moved orsqueezed in the direction of arrow B flexing or compressing inwardlyfacing projection 46 thereby causing upper arm 42 to move or rotate inthe direction of arrow C up and away from anvil assembly 26. This causesupper arm 42 to rotate to an open position relative to lower arm 44.Rotation of upper arm 42 to the open position frees anvil assembly 26from between inwardly facing projection 46 and upper arm 42.Additionally, movement of finger member 40 in the direction of arrow B,flexes the inwardly facing projection and moves inwardly facingprojection 46 slightly in the direction of arrow D to free cartridgeassembly 28 from between inwardly facing projection 46 and lower arm 44.

Thereafter, jaw restraint 10 may be drawn sideways in the direction ofarrow E away from anvil assembly 26 and cartridge assembly 28 therebyfreeing anvil assembly 26 and cartridge assembly 28 from jaw restraint10. It should be noted that, while jaw restraint 10 is illustrated anddescribed as being removed sideways in the direction of arrow E relativeto anvil assembly 26 and cartridge assembly 28, jaw restraint 10 mayalternatively be slid longitudinally over anvil assembly 26 andcartridge assembly 28 to slide jaw restraint 10 longitudinally off ofanvil assembly 26 and cartridge assembly 28.

In this manner, jaw restraint 10 firmly and robustly secures cartridgeassembly 28 relative to anvil assembly 26 during shipping therebypreventing any dislodging of staples 60 from rows of staple containingpockets 34 and 36 due to bumping, shaking etc. of anvil assembly 26 andcartridge assembly 28 during shipping.

Referring now to FIGS. 7-9, and initially with regard to FIG. 7, thereis disclosed an alternative embodiment of a jaw restraint 70. Jawrestraint 70 is similar to jaw restraint 10 and generally includes afirst or upper arm 72 and a second or lower arm 74. An inwardly facingprojection 76 is positioned between upper arm 72 and lower arm 74. Upperarm 72 is connected to inwardly facing projection 76 by a first arcuateportion 78 and lower arm 74 is connected to inwardly facing projection76 by a second arcuate portion 80. In order to prevent sideways movementof a cartridge and anvil assembly such as, for example, cartridgeassembly 28 and anvil assembly 26 described herein above, upper arm 72has an inwardly facing first lip 82 terminating an enlarged distal end84 and lower arm 74 has an inwardly facing second lip 86 terminating inan enlarged distal end 88.

Jaw restraint 70 differs from jaw restraint 10 described herein above inthat jaw restraint 70 includes a first finger member 90 extendingproximally from first arcuate portion 78 and a second finger member 92extending proximally from second arcuate portion 80. The provision offirst and second finger members 90 and 92 provide additional leverage tocompress inwardly facing projection 76 and thus separate upper arm 72from lower arm 74.

Referring now to FIGS. 8 and 9, the use of jaw restraint 70 to secureand release anvil assembly 26 and cartridge assembly 28 will now bedescribed. Referring initially to FIG. 8, in the shipping condition,upper arm 72 engages anvil assembly 26 and secures it against inwardlyfacing projection 76. First lip 82, including enlarged distal end 84,inhibits sideways movement of anvil assembly 26 relative to inwardlyfacing projection 76. Similarly, lower arm 74 engages cartridge assembly28 and second lip 86 including an enlarged distal end 88 inhibitsideways movement of cartridge assembly 26 relative to inwardly facingprojection 76. As shown, in the shipping condition, first and secondfinger members 90 and 92 are in a static or spaced apart condition.

Referring now to FIG. 9, in order to release anvil assembly 26 andcartridge assembly 28 from jaw restraint 70, proximal ends 94 and 96 offirst and second finger members 90 and 92, respectively, are squeezedtogether in the directions of arrows F and G. This compresses inwardlyfacing projection 76 causing upper arm 72 and lower arm 74 to moveoutwardly in the directions of arrows H and I to the open position. Inthis open position, anvil assembly 26 and cartridge assembly 28 are freeto be removed from jaw restraint 70. Similar to that described hereinabove with respect to jaw restraint 10, jaw restraint 70 may now bemoved sideways relative to anvil assembly 26 and cartridge assembly 28,or may be slid longitudinally along the long axes of anvil assembly 26and cartridge assembly 28, to release them from jaw restraint 70.

In this manner, jaw restraint 70, incorporating pair of finger members90 and 92, provides additional leverage for separating upper and lowerarms 72 and 74 to release anvil assembly 26 and cartridge assembly 28from jaw restraint 70.
